Controlling Telnet Users By Source Mac Addresses - HP 4800G Series Configuration Manual

Controlling Telnet Users by Source MAC Addresses

This configuration needs to be implemented by Layer 2 ACL; a Layer 2 ACL ranges from 4000 to 4999.
For the definition of ACL, refer to ACL Configuration in the Security Volume.
Follow these steps to control Telnet users by source MAC addresses:
To do...

address of the Telnet server are not in the same subnet.
